\u201cArchitectured materials designed with higher-order homogenization\u201d<\/em><\/p>\n

The primary objective of this project is to generate new architectured materials featuring non-standard properties by means of higher-order asymptotic homogenization techniques and topology optimization procedures. The team involves the following labs: Imath<\/a>, Institut Elie Cartan<\/a>, MSME<\/a>, LEM3<\/a>, LNCC<\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n

Whereas a smooth sheet of paper may fit only developable surfaces<\/a>, once folded, origami tessellations seems to fit a broader family of surfaces. This project investigates these non-trivial surfaces and the corresponding smooth mechanical models.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Cross Laminated Timber<\/a> panels, (CLT) are structural members made of several layers of board stacked crosswize to form a plate. Because wood is highly anisotropic and these panels features several scales of heterogenity (annual ring, board, layer and plate) they require advanced mechanical and structural modeling<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Higher-order elasto-plastic beam models<\/h5>\n

Higher-order beam models in small perturbation were formulated and implemented in partnership with Strains Engineering<\/a>. These models are based on asymptotic methods. The influence of the load distribution<\/a> in the beam section as well as the effect of inelastic strains<\/a> (thermal dilatation, humidity etc) are finely taken into account. This allowed us to extend the formulation to elasto-plasticity<\/a> and apply it to steel frames and also reinforced concrete<\/a>.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
